ABSTRACT:
Basic intermediate or large pore zeolites having a Constraint Index less than 12 are useful as catalysts in the dehydrogenation-aromatization of cyclie dienes, in the isomerization of olefins and in the aldol condensation, and particularly in the cyclization of acetonylacetone to 3-methyl-2-cyclopenten-1-one.
